Answer 1

Answer:

1:20 is the ratio mark me brainliest

Answer 2

Answer:

Mole fraction of NaCl in the system containing 0.5 mol of NaCl and 10 mol of $H_{2} O$ is 0.048.

Explanation:

Mole fraction = amount of a constituent in moles ÷ total amount of all constituents in a mixture in moles

Mole fraction of NaCl = Number of moles of NaCl ÷ (number of moles of NaCl + number of moles of $H_{2} O$)

Given that:

Number of moles of NaCl = 0.5 moles

Number of moles of $H_{2} O$ = 10 moles

Total number of moles = 0.5 + 10

                                      = 10.5 moles

Mole fraction of NaCl = $\frac{0.5}{10.5}$

                                   = 0.048
